產(chǎn)品別稱
智能回路電阻測(cè)試儀、智能接觸電阻測(cè)試儀、接觸電阻測(cè)試儀、開(kāi)關(guān)回路電阻測(cè)
試儀、接觸回路電阻測(cè)試儀
產(chǎn)品簡(jiǎn)介
智能回路接觸電阻測(cè)試儀是用于測(cè)量開(kāi)關(guān)、斷路器、變壓器等設(shè)備的接觸電阻、
回路電阻的專用測(cè)試設(shè)備。其采用典型的四線制測(cè)量法，通過(guò)輸出一個(gè)直流電流
，施加于被測(cè)體的兩個(gè)端鈕之間，并測(cè)量電流流過(guò)被測(cè)體所產(chǎn)生的壓降，然后通
過(guò)電壓和電流之比得出被測(cè)體的直流電阻。主要由恒流源、前置放大器、A/D轉(zhuǎn)換
器、指示裝置等部分組成。
Loop resistance tester is the special test equipment for measuring the
contact resistance and loop resistance of some devices such as switch,
circuit interrupter, and transformer and so on. It adopts the typical
four-wire method of measurement which helps get the DC resistance
through the following steps: outputting a DC current, applying the
current to the tested body by linking its two terminals, and measuring
the voltage drop when the current goes through the tested body, then
dividing the current by the voltage. In addition, it mainly consists of
constant current source, preamplifier, A/D converter, indicating device
and so on.
